ORA-19675: file string was modified during proxy copy ORACLE 报错 故障修复 远程处理

文档解释

ORA-19675: file string was modified during proxy copy

Cause: A proxy backup of the specified file failed because the file was brought on-line or otherwise modified while the proxy backup was in progress. This file was off-line or read-only when the backup began, so the file was not put into hot-backup mode, therefore no modifications are permitted while the backup is in progress.

Action: Take another backup of this file.

ORA-19675错误时指代在使用远程拷贝（Proxy Copy）时，文件已被修改，导致拷贝失败。

Oracle在此时会显示ORA-19675错误，并显示文件名。

官方解释

ORA-19675 : proxy copy of file string was modified during copy

Cause: The file was modified during the copy command between the two hosts, either through a mis-Match of checksums or through other means such as a race condition.

Action: Ensure that the correct version of the file is intact before attempting copy operations again.
